OPENUI5: Named aggregate binding data not displayed
after reading Multimodal Device Support I tried to implement it. When using a named model, binding occurs but no data is displayed.
//Controller
sap.ui.controller("view.apps.Apps", {
onInit : function () {
var oAppsModel = new sap.ui.model.json.JSONModel("model/apps.json");
this.getView().setModel(oAppsModel, "apps");
}
});
// View
sap.ui.jsview("view.apps.Apps", {
getControllerName: function() {
return "view.apps.Apps";
},
createContent: function(oController) {
var oInboxList = new sap.m.List({
inset: true,
id: "appsList",
headerText: "Apps"
});
oInboxList.bindItems("apps>/items", function(sID, oContext) {
return new sap.m.StandardListItem({
title: '{name}',
description: '{name}'
})
});
var oPage = new sap.m.Page({
title: "Apps",
content: [oInboxList]
});
return oPage;
}
});
//apps.json
{
"items": [{
"name": "ABC",
"view": ""
}, {
"name": "DEF",
"view": ""
}]
}
This view creates two empty lists. When I change the model to an unnamed model, and I update the BindPath to / items, the List is populated correctly and the values are displayed. Any ideas on what is wrong with my coding? I would really like to use the named models.

OK, just re-read the documentation. When using a named model, bindings require the ALL bindings prefix with the named model name.
oInboxList.bindItems("apps>/items", function(sID, oContext) {
return new sap.m.StandardListItem({
title: '{apps>name}',
description: '{apps>name}'
})
});
